Next, copy the zip file you downloaded earlier to the root directory of your SD card.

Once finished, disconnect your phone to the computer.

Turn off your phone.

Go to recovery: press and hold the home + volume down + power button simultaneously.

On recovery main menu select Backup/restore > Nand backup. (This will make a full backup of your existing ROM, and save it to the SD card. You can restore from this backup, if something gets messed up with the installation.)

Now go back to main menu and do a full wipe by selecting the following:

Wipe All data/factory reset

Wipe /cache
